thus might be why Subaru have pulled the info from their site maybe? (or after Gull Started sponsoring Ben Hunt perhaps)

 

covering their butt while it was was an unknown or a 'potential risk

could be as others are saying that the e10 is allowing for it to not knock due to higher knock resistance..

we can adjust the timing to get it running better on 98 or even for e10 to ensure its all running safe.

 

 

also check for all leaks etc in case its also a mechanical issue

the reading you pulled out does show there is some room for improvement as there is some knock in the upper mid range that could as well be pulling the power down

also in the low end it looks like the overall IAM reduction may be affecting the proper timing needed hence why its sluggish there

 

ideally you want the IAM to be 1.00 if the car is setup correctly

 

fueling wise it seems to want to add a bit more fuel on the top end so may need adjustments there as well depending how much the AFR actually is

My understanding is that once it has learned knock correction, when you change fuels it will take ages to bring the timing back in, so the improvement in performance you've perceived between 2 tanks of gas is almost certainly placebo/butt-dyno results. I think the massive reduction in range and improvement in performance = you just gave it more jandal.

Seeing as it looks like you had access to BTSSM you could use that to reset the ECU which will reset the Learned Values too, and the IAM will default to 0.5. Then after some spirited driving it should increase hopefully up to 1.0.
